Abstract
A therapeutic treatment device includes a housing and an incoherent light source such as a flashlamp disposed in the housing. The flashlamp provides a pulsed light output for treatment of external skin disorders. To provide light to the treatment area the housing has an opening that is disposed adjacent a skin treatment area. A reflector is mounted within the housing near proximate the light source to reflect the light to the treatment area. At least one optical filter and an iris are mounted near the opening in the housing. Power to the lamp is provided by a pulse forming circuit that can provide a variable pulse width.
